Built from Vanadium High Speed Steel (HSS-E), it delivers increased wear resistance and heat resistance compared to standard M2 HSS. The 5\/8-11 UNC thread form, plug chamfer, and 3-flute geometry combine to push chips forward ahead of the cutting zone, keeping flutes clear and reducing the risk of re-cutting. The H5 thread limit and 2B class of fit target standard commercial tolerances for through-hole threaded connections. Right-hand cutting with no coolant-through design makes this tap suited for flood or mist coolant setups.\u003c\/p\u003e\u003cp\u003eThis tap is used in production and maintenance machining environments where through-hole tapping at 5\/8-11 UNC is required. Compatible materials include aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. The plug chamfer requires a small lead-in hole depth beyond the required thread length, making it best suited for through-hole applications rather than blind holes. It is installed by machinists and toolroom technicians using CNC machining centers, drill presses with tapping attachments, or hand tapping setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium High Speed Steel (HSS-E) construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing chip packing in through-hole applications\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC thread form with H5 thread limit and 2B class of fit for standard commercial tolerances\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides gradual lead-in and is suited for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating — suitable for general-purpose machining with flood or mist coolant\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, non-interrupted thread profile, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5\/8-11 UNC spiral point plug tap for through-hole tapping in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron.

Always ensure the pilot hole diameter matches the recommended tap drill size for 5\/8-11 UNC before tapping. Secure the workpiece and verify spindle alignment before engaging the tap to avoid tap breakage or thread damage. Use appropriate cutting fluid or coolant for the workpiece material — flood coolant or cutting oil is recommended for steel and stainless applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright (uncoated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.91 inches (1-13\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 280\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.25 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2843200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729654841650,"sku":"2843200","price":94.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/773ebf8b0b72c9468cc47cada92c91d6.jpg?v=1788707277","url":"https:\/\/voomisupply.com\/products\/osg-2843200-spiral-point-tap-5-8-11-unc-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
